rifhe primary object of this inventien is to provide `a vent fortheexhaust of gas, oil, steam or other engine of'a portable nature, orservingas the power unit of a motor verrhicle of anytype'. Y

The invention '-is particularly` designed for fire engines whichfrequently require testing, adjusting and warming up of the inotor. Incold weather the house-is chilled outlet to providean escape for theexhaust when the engine is running.` j Y The present inventionl providesa vent and a connection between the exhaust pipeof the engine and thevent-.which maintains a close joint'yet admits of the engine ruimingfree, the connection being automatic. in coupling and uncoupling,thereby admittingfof the enginebeing run out of or backed into placeWould be objectionable in `fire apparatus.

While the drawings illustrate a preferred embodiment of the invention,it is tobe understood that .in adapting the means to meet specific needsland requirements, the design may be varied and changes' in the'minordetailsr of construction may be resortedto within the scope oftheinvention as claimed, without departing from thefspirit thereof.

For a full understanding of the invention and the merits thereof,reference is to be had to the following description and the drawingshereto attached, in which-v Y Figure 1 is a side viewfof an exhaustconnection embodying theinvention, showing the parts separated andpartly in section, and Figure 2v is ay central'longitudinal sectionalview showing the parts coupled. H n

`Corresponding and like parts are referred to in the followingdescription and designated in both views of thejdraw-ings4 by likereferencecharacters. 1 Y

Thevent pipe is preferablyv of sectional formation and includes auniversal joint to admit of ready coupling of the exhaust thereto whenbacking the engine into its accustomed, place in the house. As shown,the vent pipe comprises pipesectons 1 and' 2, thesection 1 extendingthrough a wall represented by the line A-B] to discharge the uponopening the window, door oil'otherf C without manipulating connectionswhich exhaust from the engine into the open air orvint'ov a sewerorotherconvenient place. univer-sal jointconnects the sections 1 and 2,1

A so thatthe free -end of the section 2 may be adjusted or positioned toreceive thecoupling `end of the 'exhaust pipe when backing'thef engineinto place. A 4ballY Ine'mber' is 'con-f` i nected in any determinate'way' to fthe 'sec-l tion 2 and isgadapted'to coact with a socket` n,member l secured'in any determinate `waylftofVK Y. vthe inner end ofthesection '1'.*5 A retaining:`

3ringjis secured to thelsocket member 4i and exi-'circles the yballmember 3 tok hold the balli member@ inf'place.` The lbolts 6Vconnecting; the 'parts 4 and k5 may 'betightened more or, less 'to gripthe member 3 between the inem?y bers 4 Vand 5 to .prevent a too freemovement thereof so that the section 2 will maintain fan adjustedposition. Y i A section of pipe 'Zfis slidable' within the section 2 andis normally held projected by open coil springs 8 interposed betweenmembers@ and 10 and mounted uponk guides 11 carried by thepart 9 andslidable in openings ofthe part 10. vThe part 10 consists of a collarand is fastto the outer end of the sec-` tion 2 and is provided withapertured ears ythrough which the guides 11 are free to move.y The part9 is fast to the outer end of the section 7 and is formed with a flaredopening 12 to receive a tapered member 13 fast to the'delivery end ofvan exhaust pipe 14: leading from the engine to be coupled to the ventpipe.` The memberv 13 consists of the segment ofla sphere and-is adaptedto i obtain a close fit within the flared opening 12 'Y in any relativeangular position vof the exhaust and vent pipes. The parts 9 and'13constitute elements of a ball and socket joint, thereby insuringacloselit when the exhaust land-,vent pipes are coupled, irrespective oftheirY relative angular, positions.

The numeral 14 designatesv the exhaust pipe yfrom the motor or engine ofthe vehicle or apparatus, with which the motor is associated an'dwhenthe exhaust and vent `pipes arecoupled, as indicated in Figure2,

the exhaust from the engine is discharged lwithout Lnecessitating theopening of any window or door of the house in which the iop CIR

engine is located. The coupling and the uncoupling between the exhaustand vent pipes is automatic and does not require any manipulation suchas the screwing or un#v screwing of the joint or like operation madenecessary in the manipulating of pipe couplings. v

Having thus described the invention, I claim:

Means for carrying off exhaust from a lire engine when operating inthe-engine"ho1ise,v the same consisting of a sectional vent pipe havingone of the sections fixed in` and-extending through a wall of the enginehouse 5 to discharge the exhaust clear thereof, r'and havinga relativelymovable section coupled to the fixed section .by al universal joint, anextension pipe slidable within the movable sectionfof the vent pipe,spring means normally holding the extension pipe projected,

'projections on the extension pipe and the movable vsection of the lVentpipe, guides iixed inthe projections vonv the. extension pipe andslidable in the projections on the movable if section'of the vent .pipeand having stops adapted to abutthe latter projections to limit theforward movement of the extension pipe, 1

an. exhaust pipe on the fire engine adapted tovfreely connectwithanddisconnect from the said extension, pipe, and a universal oint havingitselements secured upon the contiguous ends ofthe said lexhaust andextension pipes.

In testimony whereof I atlix my signature. 1
